Hey there, sorry no one else helped you out fam.

Anyway, if you've used an imageboard or any other forum, it's sorta like that. We have quite a few places where you can 'roleplay', which here means things like 'making a thread to roleplay in' or joining a thread.

How things work here, it pretty much goes like this:
If you want to make a roleplay, you make a thread in one of the roleplaying sections, and detail the roleplay you'd like to create and for others to join.
If you want to join a roleplay, you find a thread you like, and generally post a character sheet using a template found in the thread. So, here's how it'd go;

SPAGHETTI WARS: THE PASTA AWAKENS
It is the 41st Millennium. For more than a hundred minutes The Spaghetti-Lord has sat immobile on the Golden Plate of the Cupboard. He is the Chef of Pastakind by the will of the gods, and master of a million worlds by the might of his inexhaustible noodles. He is a rotting carcass writhing invisibly with power from the Dark Age of Italian. He is the Carrion Lord of the Pasterium for whom a thousand tastebuds are sacrificed every day, so that he may never truly spoil. 

Yet even in his tasteless state, the Spaghetti-lord continues his eternal vigilance. Mighty platefleets cross the pizza-infested miasma of the drivethrough, the only route between distant restaurants, their way lit by the GPS, the psychic manifestation of the Spaghetti-Lord's will. Vast armies give battle in his name in uncounted diners. Greatest amongst his soldiers are the Adeptus Rigatoni, the Space Noodles, bio-engineered super-foodstuffs. Their comrades in arms are legion: the Imperial Girandole and countless planetary defence forces, the ever vigilant Fusili and the tech-priests of the Adeptus Mezze Maniche Reigate to name only a few. But for all their multitudes, they are barely enough to hold off the ever-present threat from sushi, pizza, stale pasta - and worse. 

To be a noodle in such times is to be one amongst untold billions. It is to live in the sauciest and most delicious plate imaginable. These are the tales of those times. Forget the power of technology and gastronomy, for so much has been forgotten, never to be re-learned. Forget the promise of progress and understanding, for in the grim dark future there is only italian cuisine. There is no peace amongst the stars, only an eternity of carnage and slaughter, and the laughter of thirsting patrons.

(That would be a fluffy part, explaining the universe. Props if you get the reference)

(this would be an 'out of character' part, explaining what the players would do)
In this RP, we'll play as citizens of the Spaghetti-Lord's Empire, the Pasterium. We'll be a part of his inexhaustible noodle armies, and investigate what has happened to Penne 4, a fortress-planet that went dark.

Here's your CS:
[hider=Character Sheet]

Job: (What does he do in the Pasterium?)

Of course, that isn't ana ctual RP, just an example I pulled out of my ass obviously. But yeah, if you were interested in that thread, you'd hop in, make a reply saying "Hey I'm really interested in this, I have a CS right here, please review.", or "Hey, I'm really interested in this, I would like to 'reserve a slot' while I make a CS." or something of the sort.

Happy travels yo. Ask me if you need anything else, or one of the staff-members. (a list: [url]http://www.roleplayerguild.com/staff[/url])
